HIPAA-Compliant Patient Risk Stratification Dashboard

Design an advanced Excel dashboard that anonymizes patient data while creating a dynamic risk stratification model using conditional formatting and nested IF statements. The dashboard must include anonymized patient IDs, risk scores calculated from multiple health indicators (BMI, age, chronic conditions), and color-coded risk zones. Implement data validation rules to prevent accidental PHI exposure and create a macro that automatically updates risk categories based on new medical data inputs.
